Title: Improvements in or relating to induction manifolds for internal combustion engines
IPC: F02M1/00
Filed: 1948-02-21
Abstract: 644,113. Cylinders. CONTINENTAL MOTORS CORPORATION. Feb. 21, 1948, No. 5210. Convention date, April 9, 1942. [Class 7(ii)] In an induction manifold, which is invertible for use with either an up-draught or a down-draught carburetter, arcuate baffles 21 on the top and bottom walls and guides 22 are symmetrically arranged. The top flange bolt holes 41 are vertically above the holes in the lower flanges, or the flanges of the exhaust manifold, which may be arranged to form a hot spot opposite the connection 16 for the carburetter. As shown, the branches 20, leading to the separate cylinder, slope away from the plane 23 of symmetry, but they may be horizontal.

Title: Improvements relating to automatic controlling devices for the control surfaces of aircraft or watercraft
IPC: G05D1/08
Filed: 1934-02-16
Abstract: 414,592. Controlling aircraft and watercraft. SIEMENS & HALSKE AKT.- GES., Siemensstadt, Berlin. Feb. 16, 1934, No. 5224. Convention date, May 11, 1933. [Classes 4 and 114.] An automatic control system for aircraft or watercraft includes in addition to automatic adjusting-devices for the main control surfaces Q<1>, Q<2>, H auxiliary ailerons, or stabilizing or like control surfaces P<1>, P<2>, D or q<1>, q<2>, h operated automatically by mechanism in response to out-of-trim conditions of the craft through the medium of an auxiliary servomotor under the control of the adjusting-devices of the corresponding main control surface. In one form, aircraft altitude is controlled by an elevator H, Fig. 1, adjusted by a hydraulic motor M controlled by a slide valve S which is adjusted by a crank b<1> of a rotary armature of an electromagnetic device b operatively connected to control apparatus c, d responsive, respectively, to variation in the speed of flight and the angular velocity of the aircraft. Out of trim is corrected by adjustment of the tail plane D through worm gearing s from an electric motor E controlled by the difference of pressure on the two sides of the piston of the motor M which are connected to opposite sides of a diaphragm A connected to one end of a rod t, the other end of which is connected to a potential divider W controlling the motor. A dashpot Z in the rod t prevents actuation of the motor E due to small or rapidlyfluctuating deflections of the elevator H. A time switch may be introduced into the circuit of the motor E to reduce the sensitivity of the control and the motor E may be replaced by an hydraulic or pneumatic motor. As applied to aircraft steering, a rudder H, Fig. 2, and tail fin D are rotatably mounted on the same axis. The rudder H is controlled by an hydraulic motor M, whose controlling slide valve S is adjusted by a crank b adjusted in accordance with compass deflections from the desired course. The piston rod of the motor is connected to the rudder and is further formed in two parts connected by a dashpot e, the piston rod of which is connected to one end of a control spring f, the other end of which is fixed. Prolonged deflection of the rudder through the action of the spring f causes relative movement between the two parts of the piston rod which causes a contact k<1> to move over a contact path k of a potential divider controlling an electric motor E for adjusting through worm gearing the tail fin D. In order to prevent the motor E from adjusting the surface D during the whole time in which return energy is stored up in the dashpot e and spring f, a current interrupter U driven at constant speed by clockwork is provided in the motor circuit. The device e, e<1>, f may be dispensed with, in which case the contact path k is fixed. The motor E may be regulated according to the difference in pressure on the two sides of the piston e<1> in a manner similar to that described with reference to Fig. 1.

Title: Merchandise dispensing machine
Inventor: DRESSLER WILLIAM CHARLES
IPC: A47F1/10
Filed: 1951-03-05
Abstract: 687,992. Coin-freed machines delivering articles from piles; effecting and controlling sales. MILLS INDUSTRIES, Inc. March 5, 1951, No. 5327/51. Classes 27 and 116 Storage; articles delivered from piles. Articles are delivered from two adjacent shoots in a vending machine by an ejector 20 which in successive operations ejects first the bottom article in one shoot 12 then the bottom article in the other shoot 13, then, one at each operation, the remaining articles in the first shoot 12 and, finally, one at each operation, the remaining articles in the second shoot 13. In the first operation after both shoots 12 and 13 have been filled (Fig. 2), the ejector 20, which is carried on a square-section shaft 24 turned by a handle 25, causes a striker plate 22 which it carries to engage the lowest packet- 14a in the front shoot 13 and move it to push the lowest packet 14b in the rear shoot 12 out through a rear opening 16 normally closed by a spring-biased flap 17. When the ejector is returned to its initial position (Fig. 3), leaving the packet 14a behind, a follower 32 pivoted to a slide 31 moved along flanges 40 below the columns by the ejector 20 is raised by a spring 37, the remaining articles in the shoot 13 being supported by an L-shaped member 26 held from turning about its pivot 27 by the packets in the shoot 12. At subsequent operations of the ejector 20, the follower 32 ejects first the packet 14a and then, one by one, the remaining packets in the shoot 12 until only one packet is left in that shoot. The member 26 is then free to swing about its pivot 27 to the position shown in Fig. 4 in which it prevents the shoot 12 being filled before the other packets have been 'removed from the shoot 13. The movement of the member 26 also permits the packets in the shoot 13 to fall on to and depress the follower 32. Subsequent operation of the ejector 20 causes the striker plate 22 to engage the packet below the shoot 13 and cause it to push out the packet below the empty shoot 12; on retraction of the ejector 22 the column of packets in the shoot 13 again. depresses the follower 32. This action continues until the last packet is ejected by the ejector 22. The packets fall from the opening 16 to a tray 28 for removal from behind the front wall 29. The invention enables a display of the packets for sale to be maintained behind a window 11 in the front shoot until substantially all the packets have been sold.
